HELP. In order for an aircraft to achieve orbit it must maintain an acceleration of 29.3 m/s^2 when considering air resistant and thrust. Karencia designs a space shuttle
that when launched will travel the 35,000,000 meters required to reach orbit in
28.15 minutes. Will her rocket achieve orbit? Why or why not? (Give numeric
evidence to support your answer)

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.

Aresistor with an unknown resistance is connected in parallel to a 9 ω resistor. when both resistors are connected in parallel to an emf source of 21 v, the current through the unknown resistor is measured with an ammeter to be 4 a. what is the resistance of the unknown resistor? answer in units of ω.
